Hand drawn thorns. Very life-like. The quality of the shading makes them appear 3D so every thorn looks harmful and intimidating. You can feel the pain through this drawing as thorns are related to Jesus' crown of thorns, and it conjures up images of torture and blood shed. I can imagine thorns building up around someone in my animation, trapping them within themselves, their own demon. Acting as a barrier between them and the outside world. Much as an addict would feel inside their head.
